  The HP VAN SDN Controller is a Java-based OpenFlow controller enabling SDN solutions such as network controllers for the data center, public cloud, private cloud, and campus edge networks. This includes providing an open platform for developing experimental and special- purpose network control protocols using a built-in OpenFlow controller.

  The HP VAN SDN Controller is a platform for developing SDN applications and deploying SDN applications. The controller can be characterized as providing a Base Control Platform, a Distributed Platform for High-Availability and Scalability, and an Extensible Platform.

  B. 1.1
  C. 1.2
  D. 1.3
  D. 1.3

  ---

  Openflow 1.3.1: Support for multiple flow tables is introduced Reference: Open Flow 1.3.1 Support: Controller View https://wiki.opendaylight.org/images/d/dc/Openflow1.3_Support_for_Opendaylight.pdf

• Question 45:

  How does an HP VAN SDN Controller team provide high availability for OpenFlow switches?

  A. By using the northbound controller interface tied to a region configuration
  B. By using the northbound controller interface with a secondary interface
  C. By using the southbound controller interface tied to a region configuration
  D. By using the southbound controller interface with a secondary interface
  C. By using the southbound controller interface tied to a region configuration

  Northbound API Relative to figure 1 below, the Northbound API is the API that enables communications between the control layer and the application layer (external business applications.

  Southbound API

  Relative to Figure 1 below, the Southbound API is the API that enables communications between the control layer and the infrastructure layer (OpenFlow).

  Figure 1. ONF's SDN architecture

  *

  Putting the region configurations in place in a controller team ensures seamless failover and failback among the configured controllers for the specified network devices in a region. That is, when a master controller experiences a fault, the Role Orchestration Service ensures that a slave controller immediately assumes the master role over the group of network devices to which the failed controller was in the master role.

• Question 46:

  Which statement best describes software-defined networking (SDN)?

  A. SDN allows software to leverage the network infrastructure, enabling a centralized and policy-based approach to network provisioning and traffic forwarding.
  B. SDN allows administrators to share software, policies, templates, and applications between multiple virtual machines that are running on the same network.
  C. SDN is another name for OpenFlow, a protocol that lets switches handle traffic with OpenFlow tables rather than MAC forwarding tables and routing tables.
  D. SDN lets IT developers manage physical infrastructure devices directly without pre-defined templates or intermediary devices.
  A. SDN allows software to leverage the network infrastructure, enabling a centralized and policy-based approach to network provisioning and traffic forwarding.

• Question 49:

  Refer to the exhibit.

  

  The switches in the diagram are connected to each other using two physical cables. The network consists of two HP 3800 series switches and two HP 5900 series switches. Why is only one link displayed between switches in the OpenFlow Topology diagram on the HP VAN SDN Controller?

  A. The SPF algorithm used by the HP VAN SDN Controller only supports a single link between switches and blocks other links to stop loops. The HP VAN SDN Controller only displays the single active link between the switches
  B. Link aggregation is being used OpenFlow only displays information about the logical interface and not the physical interfaces. The HP VAN SDN Controller only displays a single link between switches
  C. Link aggregation is being used. One of the Interfaces in the bundle is down, and OpenFlow has updated the HP VAN SDN Controller with this information The HP VAN SDN Controller only displays the active link in the OpenFlow Topology diagram
  D. Spanning tree is blocking one of the ports. The HP VAN SDN Controller. Only displays the active link in the OpenFlow Topology diagram.
  B. Link aggregation is being used OpenFlow only displays information about the logical interface and not the physical interfaces. The HP VAN SDN Controller only displays a single link between switches
